Date: Thu, 29 Nov 2018 21:45:10 +0530 Message-ID: <20181129161513.31734-1-faiz_abbas@ti.com> X-Mailer: git-send-email 2.19.2 MIME-Version: 1.0 Content-Transfer-Encoding: 8bit Content-Type: text/plain X-EXCLAIMER-MD-CONFIG: e1e8a2fd-e40a-4ac6-ac9b-f7e9cc9ee180 Sender: linux-kernel-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-kernel@vger.kernel.org The following patches add driver support for MMCSD on TI's AM654 platforms. Previously I had added the support to sdhci-of-arasan driver with a separate phy driver[1]. Since then it has turned out that tuning operation (for HS200, HS400 and SDR104 speed modes) will require configuration of phy registers. This completely breaks the model of the sdhci-of-arasan driver which relies on a separate driver to configure the phy register space. Because of this, I am creating a new driver with both the sdhci and phy register spaces. This helps me use the phy registers in a future patch that adds tuning support. DT patches will be posted in a separate series.
